Well, the Model 1870 TD rifle (as opposed to those M1868s made in 1870, often called M1870s on Gunbroker and elsewhere) came with two sight configurations. All M1868s have LONG receivers with sights tight to them.

The M1870 version (just 1000 made) issued for field trial had the rear sight tight against the SHORT receiver, as on the M1870 carbine, while the "production" M1870 had the sight moved about 7/16" forward. The 1000 "trials" rifles are, like their Remington counterparts, quite scarce and desirable.
